ER Tap Collets
For Square-Shank Taps
Hold square-shank taps in ER collet chucks and tap holders to create internal threads in workpieces. To hold taps tightly in place, these collets have spring slots that grip the round part of the shank and a square opening in the base that mates with the square end. They meet DIN and ISO dimensional standards.
These collets hold inch and metric taps that have shanks that meet ANSI standards. They will not work with taps that have shanks sized to ISO, DIN, or JIS standards.
52100 alloy steel collets are made from the same tough material used to make bearings. They’re more wear-resistant than basic spring steel collets.

Quick-Change Tap Collets
Tap Collet
Tap Collet with Adjustable Clutch
Swap out taps in seconds to limit machine downtime. These collets snap into a holder with just a push. Pull back on the holder’s sleeve to release the collet—no wrenches or collet nuts required. Taps pop in and out just as easily. Press the ring on the collet’s face to replace worn taps. These collets are often used on CNC machines, manual machines, and tapping arms. Also known as Bilz-style tap adapters, they mount to rigid or compensating tap holders that accept tang-drive quick-change collets.
These collets hold inch and metric taps with shanks that meet ANSI standards. They will not work with taps that have shanks sized to ISO, DIN, or JIS standards.
Tap collets work with both rigid and compensating tap holders. Tap collets with adjustable clutch automatically stop spinning when they reach the bottom of the hole to prevent broken taps and damage to workpieces. These collets are great for blind holes and they help break up and clear out chips. They should only be used with compensating tap holders. Remove the retaining ring to adjust the torque limit for a specific tap size or workpiece material.
